Dinosaur-killing asteroid likely came from beyond Jupiter, study finds
Fox News
The asteroid that wiped out dinosaurs after slamming into the Earth 66 million years ago is believed to have come from beyond Jupiter, a new study says.
The team, led by Mario Fischer-Gödde of the University of Cologne in Germany, "measured ruthenium isotopes in the impact deposits and compared them with multiple classes of meteorites, which represent potential impactor compositions," according to a summary of the study. Greg Norman is a reporter at Fox News Digital.
"They found that the Chicxulub impactor was a carbonaceous asteroid that formed in the outer Solar System," it continued. "Additional measurements of five other impacts showed that those were due to silicate asteroids that formed in the inner Solar System."
